Migrating a z/OS stand-alone application server: Checklist

Activities for migrating a stand-alone application server to WebSphere® Application Server Version 8.0 after you generate the appropriate Job Control Language (JCL) jobs include activities related to general preparation, transaction-log clearance, and node migration. Use the following checklist as a quick reference to these activities. Follow the instructions that were generated by the z/OS® Migration Management Tool or the zmmt command to complete the process of migrating your stand-alone application server to Version 8.0.

Before you begin

Supported configurations Supported configurations:

This topic is about configuration migration, such as migrating deployment managers and federated nodes in a network deployment environment. The Application Migration Toolkit for WebSphere Application Server provides support for migrating applications from previous versions of WebSphere Application Server to the latest product version. For information about migrating applications, read more about the Application Migration Toolkit.

About this task

Key similarities to migrating a deployment manager:
  • You must still create CNTL and DATA datasets.
  • You must still allocate and mount a new configuration file system to act as the target for the new Version 8.0 configuration, either manually or using the BBOMBHFS or BBOMBZFS job.
  • You must still run the BBOWMG3B job to perform the migration.
Key differences from migrating a deployment manager:
  • You must clear the transaction logs using the BBOWMG1B job; you do not have to complete this step for a deployment manager migration.
  • You must disable Peer Restart and Recovery (PRR) mode using the BBOWMG2B job; you do not have to complete this step for a deployment manager migration.
  • There is no deployment manager node to migrate.

Procedure

  1. Prepare to migrate the application server.
    Table 1. Application server checklist . Enter your values:
    Check off Item
    __________ Make sure that you have a minimum level of Version 8.0 maintenance.

    Read Overview of migration, coexistence, and interoperability for more information.

    __________ Inventory your existing Version 5.1.x or Version 6.x configuration and capture key information.

    Read Preparing to migrate a z/OS stand-alone application server for more information.

    __________ Create CNTL and DATA datasets for each node to be migrated.

    Read Preparing to migrate a stand-alone application server using the z/OS Migration Management Tool or Preparing to migrate a stand-alone application server for z/OS using the zmmt command for more information.

    __________ Create the Version 8.0 configuration mount point, allocate a configuration file system, and mount either manually or using the BBOMBHFS or BBOMBZFS job.
    __________ Run the BBOMBCP job to copy the generated JCL procedures to your procedure library.
  2. Clear the transaction logs for the application server node.
    Table 2. Transaction logs checklist . Enter your values:
    Check off Item
    __________ Stop the server in the stand-alone application server node.
    __________ Run the BBOWMG1B job, and check for success.
    __________ Restart the application server to clear the transaction logs.
    __________ Run the BBOWMG2B job to disable PRR mode.
  3. Migrate the application server.
    Table 3. Application server checklist . Enter your values:
    Check off Item
    __________ Ensure that all servers are stopped, including the daemon server.
    __________ Run the migration jobs—including the BBOWMG3B job or the BBOWBPRO, BBOWBPRE, and BBOWBPOS jobs—by following the generated instructions; and check for success.
    __________ Start the application server.
